setup
Get your Scaleway Object Storage access keys
Credentials are created in the Scaleway console — here's the exact path:
- 1
Log in to the Scaleway console.
- 2
Open IAM (top-right menu) → "API keys" and generate a new API key.
- 3
Copy the access key and secret key — these double as S3 credentials.
- 4
Add Scaleway in Universal S3 Client, choose fr-par, nl-ams or pl-waw and paste the keys.
Console: https://console.scaleway.com/
good to know
Before you connect
Scaleway IAM API keys are also the S3 credentials — there is no separate S3 key type. Scope the key’s IAM policy to Object Storage if you want least privilege.

faq
Scaleway Object Storage — frequently asked
+ Is there a Scaleway Object Storage app for iPhone?
Universal S3 Client manages Scaleway buckets from iPhone, iPad and Mac over the S3 API — browse, upload, preview and share. It’s free and MIT-licensed.
+ Which credentials work with Scaleway’s S3 API?
Your IAM API key: the access key and secret key generated in the console’s IAM section. The app builds the https://s3.{region}.scw.cloud endpoint from your region choice.
+ Why choose an EU provider like Scaleway?
Data stays in Paris, Amsterdam or Warsaw under EU jurisdiction — a common requirement for GDPR-sensitive projects and public-sector work.
+ Does the app track what I store?
No. There is no backend, no analytics and no account — the app talks directly from your device to Scaleway’s endpoint, and credentials stay in the device Keychain.
